I am very overweight and take Effexor and now want to start Contrave to lose weight. Is there any thing to worry about with both meds together?
I guess it depends some what on the symptoms you are treating with the Effexor. Contrave doesn't contain a whole lot of bupropion and it is extended release. Nonetheless, 90 mg is close enough to 150 mg (starting daily dosage of bupropion) that I would run it by your Doctor.
Take care for now and all the best.

Interactions between your drugs
Applies to: Contrave (bupropion / naltrexone), Effexor (venlafaxine)
BuPROPion may rarely cause seizures, and combining it with other medications that can also cause seizures such as venlafaxine may increase that risk. You may be more susceptible if you are elderly, undergoing alcohol or drug withdrawal, have a history of seizures, or have a condition affecting the central nervous system such as a brain tumor or head trauma. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. You should avoid or limit the use of alcohol while being treated with these medications. Also avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medications affect you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
